How Jaime's Death Would Change Game of Thrones Forever

The preview for "Eastwatch" suggests the remaining Lannister men who are at the battle outside of Highgarden will be given the choice to bend the knee or die. Without Jaime, they won't have a leader, and many of these young men may prefer to take their chances with the queen who has dragons than to return to Cersei. Without Jaime to head up the remaining troops, the role will fall to Randyll Tarly if he survives, or possibly even Euron.

Either way, Cersei's control over these scared men will be tenuous at best, making her all the more vulnerable — and dangerous.
